The DU® Cylindrical Bushes - Inch Size, specifically part number 32DU40, are designed for a variety of industrial applications including aerospace, agricultural equipment, and food processing machinery. These self-lubricating bushings provide excellent wear resistance and low friction performance across a wide range of loads, speeds, and temperatures, making them suitable for dry running conditions as well as lubricated applications. The bushings are approved to Federal Aviation Regulations FAR 25.853 and FAR 25.855, indicating their suitability for interior aircraft applications. They can accommodate linear, oscillating, and rotating movements, enhancing their versatility in different mechanical systems. The maximum dynamic load capacity is 36,000 psi, with a maximum operating temperature of 536°F. The coefficient of friction ranges from 0.02 to 0.25, depending on operating conditions. These bushings are available in standard dimensions and can be customized to meet specific design requirements, making them a flexible choice for engineers looking for reliable bearing solutions.
Our metal-backed, PTFE-based (polytetrafluoroethy
The metal backing provides mechanical strength, while the bronze sinter layer provides a strong mechanical bond between the backing and the bearing lining. This construction promotes dimensional stability and improves thermal conductivity.
These polymer bearing linings, being predominantly PTFE, offer exceptionally low friction.
